SIFMA is Wall Street’s largest lobbying group, according to Bloomberg.

Gregg served on the Senate Banking Committee and in 2008 was one of the Republican authors of the 2008 Troubled Asset Relief Program. In 2009, he was briefly President Obama’s nominee for commerce secretary. Since 2011 he’s been an adviser to Goldman Sachs.

Gregg declined to comment to Bloomberg, and a SIFMA spokeswoman told the news agency that the search for a new CEO isn’t over.
